Channel strut fasteners

ABSTRACT

Provided herein is a fastener that may be used to secure objects to a channel strut or attach a channel strut to a structure. In an arrangement, the fastener is a fastener block configured for disposition within the interior of a channel strut. The fastener block has a body that includes at least one pair of spaced apart and parallel recesses (e.g., recessed channels) sized to engage the inward lips of the strut channel. Once the pair to recessed channels engage the strut channel lips, the fastener block is prevented from rotating. At least one aperture extends through the fastener block between the parallel recessed channels. A fastener recess (e.g., hexagon recess) is recede into the block around the aperture. A standard nut or bolt may be inserted into the fastener recess.

FIELD

The present disclosure generally relates to fasteners for channel strut framing. More specifically, a fastener arrangement is provided that allows for using standard SAE and/or metric hardware (e.g., nuts and bolts) to fastens objects to channel strut framing.

BACKGROUND

One type of channel framing is called strut channel or channel strut (used herein interchangeably), which is commonly used in the construction and electrical industries for structural support, often for supporting wiring, plumbing, or mechanical components such as air conditioning or ventilation systems. Strut channel may be utilized in numerous other industries and applications. Strut channel is usually formed from metal sheet, folded over to define an open channel with inward-curving lips to provide additional stiffness and as a location to mount interconnecting components. A fastener nut may be inserted into the interior of the channel (e.g., behind the inward curving lips) for use in securing a part to the open channel side of the strut channel. The side of the strut channel opposite the open channel and/or the sidewalls of the channel may further include repeating apertures or slots to facilitate interconnection or fastening the strut to underlying building structures.

Strut channel is standardized allowing struts and components from different manufacturers to be compatible. Basic strut channel comes in the open box section, 1⅝ by 1⅝ inch square cross section. A half-height (1⅝ inch wide, 13/16 inch tall) cross section version is also available. A deep channel 2 7/16 inches tall and 1⅝ inch wide is also manufactured. Additionally, a half-width ( 13/16 inch wide) version is also available.

In any arrangement, the inwards-facing lips on the open side of strut channel are routinely used to mount specialized nuts, braces, connecting angles, and other types of interconnection mechanisms or devices to join lengths of strut channel together or connect pipes, wire, other structures, threaded rod, bolts, or walls into a strut channel structural system.

SUMMARY

Aspects of the presented disclosure are based on the realization that existing strut channel attachments methods typically require the use of specialized fasteners. That is, most strut channel attachment systems require the use of specialized fastener nuts or bolts that engage within the interior of the strut channel. Difficulties arise when a user wants to use standard fastening hardware (e.g., nuts and bolts of various standard sizes both SAE and metric. Previous attachment methods and systems require specific hardware (e.g., channel nut, channel bolt). If a user wants to utilize a different sized fastener (e.g., diameter), the use must have the specialized hardware of the desired size. This creates a cumbersome and costly requirement for a user who may need to vary a fastener size based on the specific usage, which can vary for each attachment encountered.

Provided herein is a fastener that may be used to secure objects to a channel strut or attach a channel strut to a structure. In an arrangement, the fastener is a fastener block configured for disposition within the interior of a channel strut. The fastener block has a body that includes at least one pair of spaced apart and parallel recesses (e.g., recessed channels) sized to engage the inward lips of the strut channel. Once the pair to recessed channels engage the strut channel lips, the fastener block is prevented from rotating. At least one aperture extends through the fastener block between the parallel recessed channels. A fastener recess (e.g., hexagon recess) is recessed into the block around the aperture. A standard nut or bolt may be inserted into the fastener recess. Once disposed within the fastener recess, the nut or bolt is secured relative to the strut channel and prevented from rotating. A user may then engage the nut or bolt with a mating fastener.

In an arrangement, the fastener block includes first and second fastener recesses on opposing surfaces (e.g., upper and lower surfaces of the fastener block). In this arrangement, the fastener block may include two pairs of parallel recessed channels, one pair on its upper surface and one pair on its lower surface. In such an arrangement, the fastener recesses on the upper and lower surfaces may have different cross-dimensions permitting the fastener block to engage differently sized nuts or bolts.

In a further arrangement, the fastener block may include multiple apertures between the parallel recessed channels. In such an arrangement one or both sides of the multiple apertures may include fastener recesses, each of which may have a different cross-dimension. In such an arrangement, the fastener block may be configured for use with multiple different sized fasteners including standard and metric sizes.

DETAILED DESCRIPTION

Reference will now be made to the accompanying drawings, which at least assist in illustrating the various pertinent features of the presented inventions. The following description is presented for purposes of illustration and description and is not intended to limit the inventions to the forms disclosed herein. Consequently, variations and modifications commensurate with the following teachings, and skill and knowledge of the relevant art, are within the scope of the presented inventions. The embodiments described herein are further intended to explain the best modes known of practicing the inventions and to enable others skilled in the art to utilize the inventions in such, or other embodiments and with various modifications required by the particular application(s) or use(s) of the presented inventions.

FIG. 1A is a perspective view of a section of a channel strut 100 and FIG. 1B is a cross-sectional view of the strut 100. As shown, the strut 100 has three sidewall surfaces and a generally open side surface. More specifically, the strut 100 may include a closed or bottom-end 102 (which may have various apertures formed therein), a first side-wall surface 104 a and a second sidewall surface 104 b (collectively, sidewalls 104). Disposed on the free ends of the sidewalls 104 are a first flange 106 a and a second flange 106 b, respectively, (collectively, flanges 106). The first flange 106 a, may include a first inwardly projecting portion 108 a and a first upwardly projecting portion 110 a (e.g., lip). Likewise, the second flange 106 b may include a second inwardly projecting portion 108 b and a second upwardly projecting portion 110 b (e.g., lip). Collectively, the inward and upward projections of the flanges 106 define inwardly curving lips on the open side of the channel strut. Such flanges/lips provide additional stiffness to the strut channel as well as a location to mount interconnecting components. As shown in FIG. 1B, the side of the strut 100 opposite the end-surface 102 has an opening 112 between the facing or inside surfaces of the flanges 106. The opening 112 has a width of d1 between the first upwardly projection portion 108 a and the second upwardly projecting portion 108 b. Further, the channel strut 100 has a channel width of d2 from the inner surface of the first sidewall 104 a to the inner surface of the second sidewall 104 b.

As illustrated in FIG. 2A, a fastener block 120, in accordance with the present disclosure, may be disposed through the opening 112 in the strut channel 100. The fastener block 120 may then be positioned (e.g., rotated) to extend across the top surfaces of the upward projections 110 a and 110 b and between the inside surfaces of the sidewalls 104. Once the fastener block 120 is positioned across the opening 112, a fastener such as a bolt 162 may engage the fastener block 120 to secure and object 164 against the surface of the channel strut 100.

As noted above, prior strut channel fasteners are formed as specialized fastener nuts or specialized fastener bolts configured to engage with the strut channel. Such prior fasteners have a predetermined nut or bolt diameter. In these arrangements, a specialized fastener nut may receive a standard bolt and a standardized fastener bolt may engage a standard nut. However, such prior fastening systems cannot be utilized with both standard SAE and/or metric nuts and bolts. If a user wants to utilize different sized fastener hardware, the user needs to have a different sized specialized fastener. That is, such prior art specialized fasteners cannot accommodate differently sized fastener hardware (e.g., nuts and bolts).

FIGS. 3A and 3B illustrate top and bottom perspective views of a fastener block 120 in accordance with the present disclosure. FIGS. 4A-4C illustrate top, side and bottom views of the fastener block 120. In the illustrated embodiment, the fastener block 120 is roughly defined as a rectangular prismatic body having an upper surface 122, a lower surface 124, and four side surfaces extending between the upper surface 122 and the lower surface 124. Specifically, the body of the fastener block 120 includes opposing side surfaces 126 a, 126 b, a front side surface 128 a and a rear side surface 128 b. In the embodiment illustrated in FIG. 3A-4C, the fastener block 120 incudes a plurality of fastener recesses 140 a-d (hereafter 140 unless specifically referenced) formed into its upper and lower surfaces. The fastener recesses 140 each extend partway into the body of the fastener block 120.

Upper and lower pairs of channels 150 a, 150 b are formed into the upper and lower surfaces of the fastener block 120 and extend between the front and rear side surfaces 128 of the fastener block 120. The upper or lower pairs of channels are configured to engage with the first upwardly projecting portion 110 a (e.g., first lip) and the second upwardly projecting portion 110 b (e.g., second lip) of the channel strut 100 when the fastener block 120 is disposed therein. This is best illustrated in FIGS. 2A and 2C, which show the lower pair of channels 150 b engaging the upwardly projection portion of the channel flanges/lips 110. As will be appreciated, the fastener block is resistant to rotating/turning when the channels are fully engaged with the channel flanges/lips.

Referring to FIG. 3A, the fastener block 120 includes two fastener recesses 140 a and 140 b that are recessed into the upper surface 122. Each fastener recess 140 a and 140 b surrounds an aperture 144 a and 144 b, respectively, which passes through the body of the fastener block 120. In the illustrated embodiment, these recesses 140 are hexagonal-shaped recesses, which are sized to receive correspondingly sized hexagonal fasteners. That is, each recess may be sized to receive a hexagonal nut or a hexagonal head of a bolt. In this specific embodiment, the first recess 140 a is sized to receive a 5/16 inch hexagonal nut or bolt while the second recess 140 b is sized to receive a ¼ inch hexagonal nut or bolt. In various embodiments, the block may include surface indicia showing the size of the fastener recesses. As further illustrated in FIG. 3B, the fastener block 120 includes two additional fastener recesses 140 c and 140 d that are recessed into its lower surface 124. Each of the lower fastener recesses 140 c and 140 d are likewise disposed around one of the apertures 144 a and 144 b. In this regard, first and second opposing fastener recesses may be disposed around both an upper and lower end of each aperture. In the illustrated embodiment, the lower fastener recesses may have dimensions that are different than the dimensions of the upper fastener recesses, which may themselves be different. By way of example, the third recess 140 c is sized to receive an 8 mm hexagonal nut or bolt while the fourth recess 140 c is sized to receive a 6 mm hexagonal nut or bolt. In this regard, a single fastener block 120 may be utilized with a variety of differently sized fastener hardware.

FIGS. 5A-5C illustrate another embodiment of a fastener block 120 a. This embodiment of the fastener block 120 a shares many of the same attributes as the fastener block 120 described in relation to FIGS. 3A-4C and like reference numeral are utilized to refer to like elements. As shown, this embodiment the fastener block 120 a includes a single aperture 144 that extends through the block between its upper surface 122 and its lower surface 124. Likewise, the fastener block 120 a includes a single upper hexagonal fastener recess 141 that is recessed into the upper surface 122 and a single lower hexagonal fastener recess that is recessed into the lower surface 124. In such an embodiment, the fastener block may allow use with two differently sized standard hexagonal bolts and/or nuts.

Though previously discussed as utilizing hexagonal fastener recesses, it will be appreciated that the fastener block of the present disclosure is not limited any specific recess configuration. That is, the fastener recess(es) may have any appropriate shape to match any corresponding fastener. FIGS. 6A-6C illustrates three nonlimiting embodiments of fastener blocks 120 b, 120 c and 120 d, respectively, which utilize various differently shaped fastener recesses in their top and/or bottom surfaces. By way of example, the fastener block 120 b of FIG. 6A utilizes a four-pointed star fastener recess 145, the fastener block 120 c of FIG. 6B utilizes a diamond-shaped fastener recess and the fastener block 120 d of FIG. 6C utilizes a multi-pointed star-shaped fastener recess 149. Other variations are possible. Of further note, the shape of the fastener recesses may vary between the top surface and the bottom surface. What is important is that the fastener recess be configured to at least partially receive a fastener (e.g., nut or bolt head) and prevent the fastener from turning while the fastener held by the fattener block is being engaged by a matching fastener.

The disclosed fastener blocks may be utilized to position either a standard nut or a standard bolt within a strut channel to allow for attachment thereto. As illustrated in FIG. 7A, the fastener block 120 is shown with a standard hexagonal nut 160 disposed within the fastener recess 140 within its top surface. In the illustrated embodiment, the depth of the fastener recess 140 is equal to the thickness of the nut 160. However, this is not a requirement. Once the hexagonal nut 160 is disposed within the fastener recess 140, and the fastener block 120 engages a strut channel (not shown), a bolt may extend through the fastener block aperture 144 to engage the nut 160. FIG. 7B illustrates a configuration where the fastener block 120 receives the bolt 162, which extends through the central aperture of the fastener block until the hexagonal head of the bolt is received within the fastener recess 140. Once the fastener block is engaged with a strut channel (not shown), the hexagonal nut may engage the threads on the distal end of the supported bolt 162.

As mentioned above with respect to FIGS. 2A-2C, a fastener block 120 may be inserted into the open channel of the strut 100 and rotated to secure the fastener within the strut 100. FIG. 8 illustrates a fastener block disposed between the sidewalls 104 of a strut channel 100. For clarity, the flanges/lips are removed though the inside edges of the flanges are shown in phantom to illustrate the width d1 of the channel opening 112. In an embodiment, fastener 100 has a width ‘w’ that is narrow enough to be inserted into the channel opening 112. For example, as illustrated in the top position (e.g., position 1) in FIG. 8 , the fastener width w is less than opening width d1 of the strut channel 112. In this example, width w extends between the front and rear side surfaces 128 a and 128 b. Once the fastener block 120 is inserted into the strut 100, the fastener block 120 may be rotated as shown in the middle position (e.g., position 2) of FIG. 8 . In the illustrated embodiment, the fastener block 120 includes opposite rounded side-surface corners 130 a and 130 b. A first rounded corner 130 a extends between the front side surface 128 a and the second opposing side surface 126 b. The second rounded corner 130 b extends between the first opposing side surface 126 a and the rearward surface 128 b. The rounded corners 130 a, 130 b allow the fastener block 120 to be rotated from the middle position to the bottom position (e.g., position 3) in FIG. 8 . That is, if a distance measured from the first rounded corner 130 a to the second rounded corner 130 b is less than the width d2 of the strut channel, the fastener block 130 may rotate about an axis normal to its top and/or bottom surfaces while disposed within the channel. That is, the rounded corners and/or opposing corners having a maximum length therebetween that is less than the length of the channel width allow turning the fastener block.

The ability to rotate the fastener block about an axis normal to its upper surface limits an overall length of a fastener block and, therefore, the number of fastener recesses that the fastener block may contain. However, it will be appreciated that the fastener block may be rotated about an axis that is perpendicular to an axis normal to the top and/or bottom surface of the fastener block. This is illustrated in FIGS. 9A-9C. As shown, the fastener block 120 may be inserted into the opening 112 of the strut channel 100 as long as the thickness (e.g., between the top and bottom surfaces 122, 124) of the fastener block 120 is less than the width of the opening. See FIG. 9A. Once within the strut channel, the fastener block may be rotated around its long axis (i.e., normal to the paper; see FIG. 9B) to align the channels 150 with the lips 110 of the channel opening. The fastener block may then be pulled into engagement with the lips 110. See FIG. 9C.

FIG. 10 illustrates top, side and bottom views of one embodiment of a fastener block 220 having a length that prevents rotation within a channel strut about an axis normal to its top surface. This embodiment of the fastener block 220 shares many of the same attributes as the fastener block 120 described in relation to FIGS. 3A-4C and like reference numeral are utilized to refer to like elements. This embodiment of the fastener block includes a set of three fastener recesses 240 a-240 c on its top surface 122 and a set of three fastener recesses 240 d-240 f on its bottom surface 124. The six total fastener recesses 240 a-f are disposed on opposing sides of three apertures 244 a-c that pass through the body of the fastener block between its upper and lower surfaces. In this embodiment, each of the fastener recesses may be aligned with center of the fastener block (e.g., midway between the channels 150) such that an object attached to a channel strut may be aligned with a center of the channel opening. In addition, the six fastener recesses 240 a-f may each be different sized allowing a single fastener block to be utilized with standard nuts and bolts having six different diameters.

FIGS. 11A-11D illustrate yet another version of a fastener block 320. This embodiment of the fastener block 320 is configured for receipt within a half channel 300 and may require insertion through an end surface of the channel. The fastener block includes six differently sized fastener recesses 340 a-f (only three shown) disposed within the upper and lower surfaces 122, 124 of the fastener block 320. As with the previous fastener blocks, the upper and lower surfaces include channels 150 that are configured to engage the lips of a strut channel.

One difficulty in positioning a fastener block within a strut channel is that the fastener block may move along the channel. This is especially problematic when the strut is vertically positioned. That is, a fastener block disposed within the channel tends to fall to the bottom of the strut. A user is required to hold the fastener block in place. To facilitate maintaining the position of a fastener block in a desired position once inserted into a strut channel, the embodiment illustrated in FIGS. 11A-11D includes a number of small protrusions 170 formed on the fastener block's side surfaces 126 a, 126 b, which are positioned between opposing sidewalls 302 and 304 of the strut channel. As defined above, the channel width of the strut channel between the inside surfaces of the opposing sidewalls may be defined as having a distance or width of ‘d2’. This width d2 is wider than a distance between the opposing side surfaces 126 a and 126 b of the fastener block to allow the fastener block to be positioned therebetween. However, a width or distance ‘d3’ between the outside surfaces of opposing protrusions 170 a, 170 b (see FIG. 11C) is greater than the channel width d2. In this regard, the opposing protrusions engage the opposing inside surfaces of the channel 300 when the fastener block is disposed therein. See FIG. 11D. This engagement provides sufficient friction to hold the fastener block 320 in a desired location within the strut channel 300. Though discussed in relation to the embodiment of FIGS. 11A-11D, it will be appreciated that such protrusions may be incorporated with any of the fastener blocks disclosed herein.

The protrusions 170 are preferably formed of a malleable material such that they may deform to allow a fastener block to be positioned within a strut channel. In one embodiment, the protrusions are integrally formed with the fastener block. In such an arrangement, the fastener block and the protrusions may be formed in, without limitation, a 3-D printing process or a molding process (e.g., injection molding). In one embodiment, the fastener block and, if included, the protrusions are formed of a polymeric material. In another embodiment, the fastener block and, if included, the protrusions are formed from a metallic material. The fastener block may be made of any material that provides sufficient structural rigidity.

Additional features may be incorporated into the fastener blocks to maintain the fastener blocks in a desired location within a strut channel. Referring to FIG. 4B, it will be noted that each of the channels 150 formed within the body of the fastener block may have sidewalls 153 a, 153 b that are angled or tapered to a bottom surface 155. The width of the bottom surface ‘w1’ may be narrower that the width ‘w2’ of the upper end of upwardly projecting portion 110 b or lip of the flanges. See FIG. 1B. (e.g., lip). More specifically, the sidewalls may taper from an opening that is wider than the upper end of the lip to the bottom surface of the channel. In this regard, the upper end of the projection portion/lip may wedge into the channel 150 when a user applies a compressive force between the fastener block and the strut channel.

FIG. 12 illustrates a yet further embodiment of a fastener block 420. This fastener block again has a pair of upper channels 150 a and fastener recesses formed into its upper surface. The fastener block may additionally include a pair of lower channels 150 b and fastener recesses formed in its lower surface 124. To provide additional frictional contact between the fastener block and the lips of a strut channel, the channels 150 may include one or more deflectable protrusions or partial webs 180 that extend from the sidewall surfaces 153 a, 153 b of the channels 150. These partial webs may deflect and provide a frictional fit between the channel lips and the fastener block when the fastener block is compressed against the channel lips. As with the protrusions formed on the side surfaces of the fasteners, the partial webs are preferably formed of a malleable material such that they may deform to allow a fastener block to be fixedly positioned within a strut channel.

An additional problem that may be encountered when utilizing the fastener block is maintaining either a nut or bolt within a fastener recess during installation. That is, the nut or bolt may fall out of the fastener recess. To provide a frictional fit between the fastener recess and an inserted fastener (e.g., nut or bolt head), the fastener recesses may include a protruding ridge that extends from a sidewall of the fastener recess into the open interior of the recess. This is illustrated in FIG. 3A which shows a fastener ridge 190 disposed on the sidewall of the first fastener recess 140 a. As shown, this embodiment of the fastener ridge 190 is generally triangular-shaped and extends from the top surface 122 of the fastener block to the bottom of the first fastener recess. The ridge may provide a location within the fastener recess that has a cross-dimension that is slightly smaller than a corresponding cross-dimension of a fastener that will be disposed within the recess. Accordingly, if the ridge is formed of a malleable material, it may deform when a fastener is pressed into the recess and thereby provide a frictional fit with the inserted fastener. Such a ridge or other protrusion may be integrally formed with the fastener block.

Additional variations exist for the fastener blocks. FIG. 13 illustrate a further embodiment of a fastener block 520. As illustrated, the fastener block is configured for use in a shallow strut channel 100. In such an arrangement, there may not be enough space to utilize a dual sided fastener block that may receive two or more differently sized fasteners. In such an arrangement, a single sided fastener block may be utilized having a fastener recess 140 on a top surface 122 that surround an aperture 144 passing through the fastener block. Two channels 150 may be formed on the lower surface of the fastener block for engaging the lips of the strut channel. Though not permitting use of multiple sized fasteners, this embodiment still allows use of standard nuts and bolts.

FIGS. 14A and 14B illustrate use of a fastener block 120 to secure a strut channel 100 to a wall surface 114. As illustrated, a bolt 162 may be disposed through a first surface of the fastener block 120 such that a head of the bolt is disposed within a fattener recess. A second attachment element such as screw 166 may pass through the fastener block 120 form an opposite surface to engage the wall 114. At this time. The bolt 162 may pass through an aperture in the strut channel 100 and a nut may engage the bolt 162 to secure the strut channel 100 to the wall 114.

The presented fasteners provide a number of benefits over prior strut fasteners. In various embodiments, the fasteners may be made of non-reactive materials (e.g., polymeric materials) that isolate potentially dissimilar materials (e.g., strut channel and bolt) to prevent, for example, galling, corrosion, and other negative effects that arise if the components are incompatible. The disclosed fasteners may also provide electrical isolation. The fasteners also allow use of standard nuts and bolts of varying sizes thereby eliminating the use of a wide variety of differently sized diameter and thread configurations of prior specialized fasteners. Further, standard or metric nuts and bolts may be utilized interchangeably with a single fastener. Prior fasteners attempt to use springs, wings, threading of components, etc., to hold the fattener in place during application. Such methods do not fully solve the issue of the product moving within the channel during installation and or attachment. That is, current methods do not adequately hold the fastener prior, and during installation, in positioning incrementally, and tightening of the fastener. The use of the malleable protrusions on one or more outer surfaces of the presented fasteners provide a secure fit between the fastener and the strut channel during the application process.
